摘　　要：为了加深学生对位移法及阶梯梁位移计算的理解,以阶梯式简支梁为例,分别利用积分法、常规图乘法、刚度叠加法及位移法求解了阶梯式简支梁的位移。计算结果表明:利用位移法求解阶梯式简支梁的位移具有独特的优势,可显著减少计算工作量并提高计算准确率,值得在教学过程中推广。In order to deepen students'understanding of displacement method and displacement calculation of a stepped beam,the displacement of a stepped simply-supported beam is independently solved by integral method,conventional graph multiplication method,stiffness superposition method and displacement method respectively.The calculation results show that the displacement method to solve the displacement of the stepped simply-supported beam has a unique advantage.It can significantly reduce the computational workload and improve the accuracy of the calculation,which is worth popularizing in the teaching process.
